Abstract: The present invention provides a supply identifier, which takes precise decision on the range of the external supply to manage a proper internal supply to the core of the IC by controlling a regulator or a switch connected to external supply. This supply identifier, defers the decision till everything that influence the decision settles after power-up, then makes a decision only once depending on the external supply range and switches itself off keeping the decision stored, to avoid noise induced wrong behavior and to reduce power consumption.
